TUSB3410: Access I2C devices by Linux HID driver

Hi YaoTien,

We have limited TUSB3410 linux support, but I am actively trying to see if I can get you an answer to these questions. I will let you know by end of day tomorrow.

Thanks,

Ryan

Hi Ryan,

Do you have any update?

Thanks.

Hi YaoTien,

1. I am not 100% sure on this one, I believe most control is done via the EEPROM Burner.

2. Please read this App Note and see if it has the solution you are looking for: https://www.ti.com/lit/an/slla154/slla154.pdf .

Thanks,

Hi Ryan,

This document didn't say how to control I2C device by Linux HID driver. The Windows driver also use HID driver to control I2C devices by HID driver. I think the command and control procedure is similarly. Could you help to share it or any sample code?

Thanks.

Hi YaoTien,

If you have not already, I would recommend looking at the software development tab on the TUSB3410 page and see if there is any extra software there that may be useful. Otherwise, I don't believe we have any extra sample code. E2E may also be a good place to look, such at this thread: https://e2e.ti.com/support/interface-group/interface/f/interface-forum/604386/tusb3410-tusb3410-supporting-virtual-com-port-and-hid-question.

Thanks,

Ryan
